That is what I was afraid of. We were camping when it happened. They guy in the next spot had a white Ford and was in the line of fire. I could see a dent and a soot mark in his future. Luckily, my daughter was able to fish the ball out.

 

4inch turbo back exhaust would be good for you what ur looking for.

I have a MBRP 5" inch turbo back straight pipe and its not that bad in the cab at all, my engine is louder than the exhaust cruising at 70mph.

 

Straight pipe it, slap a stack on er and be done with it. Just make sure the lower lip of the stack is above the cab to reduce the drone.
